pp碰撞中的色重联和类流花样

Color reconnection and flow-like patterns in pp collisions

Antonio Ortiz, Peter Christiansen, Eleazar Cuautle, Ivonne Maldonado, Guy Paic

摘要:

越来越多的数据收集在大型强子对撞机,我们面临着可能存在的流动pp碰撞。在这项工作中,我们表明,PYTHIA 8产生流状效应的事件与多个硬亚碰撞由于颜色字符串形成之间的最终部分子从独立的硬散射,所谓的颜色重连。我们目前的研究不同的识别强子观测值在pp碰撞在7 TeV的调4C。研究已经完成了最小偏差和多重性间隔的事件,并没有颜色重连接,以隔离流动样的效果。

英文摘要:

Increasingly, with the data collected at the LHC we are confronted with the possible existence of flow in pp collisions. In this work we show that PYTHIA 8 produces flow-like effects in events with multiple hard subcollisions due to color string formations between final partons from independent hard scatterings, the so called color reconnection. We present studies of different identified hadron observables in pp collisions at 7 TeV with the tune 4C. Studies have been done both for minimum bias and multiplicity intervals in events with and without color reconnection to isolate the flow-like effect.
